Can Synthetic Data Boost the Training of Deep Acoustic Vehicle Counting Networks?

1 code implementation17 Jan 2024 Stefano Damiano, Luca Bondi, Shabnam Ghaffarzadegan, Andre Guntoro, Toon van Waterschoot

In the design of traffic monitoring solutions for optimizing the urban mobility infrastructure, acoustic vehicle counting models have received attention due to their cost effectiveness and energy efficiency.

Microphone Subset Selection for the Weighted Prediction Error Algorithm using a Group Sparsity Penalty

no code implementations16 Jan 2024 Anselm Lohmann, Toon van Waterschoot, Joerg Bitzer, Simon Doclo

Reverberation can severely degrade the quality of speech signals recorded using microphones in an enclosure.

End-to-end Transfer Learning for Speaker-independent Cross-language Speech Emotion Recognition

no code implementations22 Nov 2023 Duowei Tang, Peter Kuppens, Luc Geurts, Toon van Waterschoot

We use the wav2vec 2. 0 pre-trained model to transform audio time-domain waveforms from different languages, different speakers and different recording conditions into a feature space shared by multiple languages, thereby it reduces the language variabilities in the speech features.

Sampling Rate Offset Estimation and Compensation for Distributed Adaptive Node-Specific Signal Estimation in Wireless Acoustic Sensor Networks

no code implementations4 Nov 2022 Paul Didier, Toon van Waterschoot, Simon Doclo, Marc Moonen

Sampling rate offsets (SROs) between devices in a heterogeneous wireless acoustic sensor network (WASN) can hinder the ability of distributed adaptive algorithms to perform as intended when they rely on coherent signal processing.

Quantifying and Computing Covariance Uncertainty

no code implementations6 Oct 2021 Filip Elvander, Johan Karlsson, Toon van Waterschoot

In this work, we consider the problem of bounding the values of a covariance function corresponding to a continuous-time stationary stochastic process or signal.

Low-Complexity Steered Response Power Mapping based on Nyquist-Shannon Sampling

2 code implementations17 Dec 2020 Thomas Dietzen, Enzo De Sena, Toon van Waterschoot

The steered response power (SRP) approach to acoustic source localization computes a map of the acoustic scene from the frequency-weighted output power of a beamformer steered towards a set of candidate locations.

A multi-layered energy consumption model for smart wireless acoustic sensor networks

1 code implementation17 Dec 2018 Gert Dekkers, Fernando Rosas, Steven Lauwereins, Sreeraj Rajendran, Sofie Pollin, Bart Vanrumste, Toon van Waterschoot, Marian Verhelst, Peter Karsmakers

This model provides a first step of exploration prior to custom design of a smart wireless acoustic sensor, and also can be used to compare the energy consumption of different protocols.
